2.8" touch screen-unknown driver chip 0

The main libraries folder should only contain what was in the original Arduino installation. All libraries that you download yourself should go in the sketchbook library folder.

Using Adafruit 2.8 inch TFT Arduino Shield Pinout

It still thinks it is using the shield pinout. Make sure you have only one copy of the TFTLCD library and that it has been edited to not use the shield pinout.

Any suggestions?

Any suggestions?

Nothing more than has already been said: Make sure you have only one copy of the TFTLCD library and that it has been edited to not use the shield pinout. Clearly the compiler is finding "#define USE_ADAFRUIT_SHIELD_PINOUT" during compilation.

If you can't fix it in the library, you can always wire up the breakout using the shield pinouts.

[walterstx]

Where can I find the shield pinout information?

[adafruit_support_bill]

It uses digital pins 5-13 and analog 0-3. The schematic shows the exact pin mapping:

[walterstx]

Works fine using the shield pinout.

Thanks.

[adafruit_support_bill]

Good! I'm glad that worked for you.

I am getting the same issue.. I am using the 2.8" touch Shield with Arduino Uno and as i am trying to use any of the examples(Graphical, paint shield, etc...) I am getting the error"

Unknown LCD driver chip: 0

I do not know the next step to take.. Please let me know if anyone has any ideas.

[pburgess]

Good Day - Could you please try downloading and installing this earlier version of the library, see if that helps?

https://github.com/adafruit/TFTLCD-Libr ... 5263787d1f

If that works, then I have bugs to hunt in the current library. If that still doesn't fix it, the shield is defective and we'll issue a replacement. Please let me know either way, thanks!

Hi,

I'm having a similar problem with the 2.8" TFT Touch Screen shield. I'm using an Arduino Uno. Adafruit_TFTLCD.h contains the line "#define USE_ADAFRUIT_SHIELD_PINOUT". But when I start the graphicstest example I get the following output on the serial monitor:

Code: Select all

TFT LCD test
Using Adafruit 2.8" TFT Arduino Shield Pinout
Unknown LCD driver chip: 5555
If using the Adafruit 2.8" TFT Arduino shield, the line:
  #define USE_ADAFRUIT_SHIELD_PINOUT
should appear in the library header (Adafruit_TFT.h).
If using the breakout board, it should NOT be #defined!
Also if using the breakout, double-check that all wiring
matches the tutorial.


I'm using the latest 1.0.3 Arduino IDE. Here is the output from a verbose build. Any ideas what to try next?

Thanks,
Rob.

Hi Robert,

Would you mind trying something for me? With the 'newer' (but seemingly broken) library, in any of the example sketches, try forcing the 'identifier' value and see if the sketch then runs normally. i.e. comment out:

Code: Select all

  uint16_t identifier = tft.readID();

and in its place add:

Code: Select all

  uint16_t identifier = 0x7575;

If this helps, then it greatly narrows down the bug hunt!

Much appreciated, thanks!

[RobertCL]

Hi,

Yep, that works ok if I do that. Hardcoding the id to 0x7575 works fine. Using the graphicstest example I get a little demo on the screen and the following output on the serial console. The other examples (rotate and paint) work ok as well.

Looks like you have a problem in your id reading code then Though I must admit I cant imagine what because I was trying to port the code over to a netduino and was getting nowhere reading the ID, so I ended up looking at the datasheet and from what I could work out the code should work. Now that I know what sort of chip I have I might keep going with trying to make the netduino code work.

Let me know if there is anything else you want me to test.

Cheers,
Rob.

I think I know the offending line, or close to it. Since my shield doesn't exhibit the symptom, would you be willing to test a few small changes? Also, I'm swamped on another project at the moment, so I hope you're okay using the 'hacked' library in the interim. We'll get to the bottom of this yet!

[RobertCL]

Yes, no worries, happy to test out a few changes. Let me know what needs changing and I'll give it a go.

And yes, I'm fine with just using the id now I know which one to use

Cheers,
Rob.
